Reaction Steps

A hot mixture of 1.45 g of the product of Step B in 15 ml of hot dioxane was cooled and 0.3 ml of hydrazine hydrate was added thereto. The mixture was stirred for 50 minutes at 20° C. and 7.5 ml of N hydrochloric acid were added thereto. The mixture was stirred for 15 hours and vacuum filtered. The filtrate was rinsed with water and the filtrate was evaporated to dryness to obtain 0.914 g of cis 4-thiocyanatomethyl-3-amino-2-oxo-azetidine hydrochloride.
